Hernandez Plumbing has provided licensed residential repair in Miami since 1972. From Brickell high-rises to Coconut Grove historic homes, we know the leaks, backups, and no-hot-water calls these properties actually run into.
Tropical humidity, summer storms, and aging pipes make small leaks and backups worse if you wait. Our crews work Miami homes and condos every week, we can walk the quote in Spanish when that helps, and we quote the repair before walls come open — $49 evaluation, 24/7 when you need a shutoff.
We also serve Coconut Grove from our Miami team.
What we see most in Miami residential plumbing
Tropical humidity and frequent summer rain drive corrosion, flooding stress on trench drains, and hurricane-season surge on building systems.
- •Cast-iron deterioration in historic bungalows
- •High-rise riser and booster failures
- •Flooding and garage trench-drain overload
- •Humidity-driven pipe and heater corrosion
Historic homes beside Class-A towers and 24/7 hospitality—repairs must respect both eras and occupancy.
Residential plumbing by neighborhood
Downtown Miami
Downtown towers often share pipes with shops and offices below. We work with building staff so your unit gets fixed without shutting down the rest of the building.
Brickell
Brickell towers often need after-hours access and building approval. We isolate the unit so the rest of the stack stays in service.
Little Havana
Older Little Havana homes often have galvanized or cast-iron pipes. We explain the repair in English or Spanish and quote before we open walls.
Wynwood
Wynwood lofts and gallery buildings often have tight kitchen and bath layouts. We repair on short timelines so you are not down through a weekend event.
Coconut Grove
Grove bungalows often back up from old pipes and tree roots. We find the blockage first so you are not paying to dig until we know where.
Plus 2 more neighborhoods we serve
We also serve Coconut Creek, Cutler Bay, Homestead, Miami Beach, Miramar, North Miami Beach, Opa-locka, Pompano Beach, and South Miami from our Miami team, with the same residential backflow testing & certification coverage.
